INVENTOR ATTORNEY Patented July 14, 1931 UNITED STATES JOHN ROCCIOLA, 0F LODI, NEW ZI'ZEZIEtSIElS Z EMZBALMING PUMP I Application filed February 5, 1930. Serial No. 426,145.

This invention relates to pumps especially designed for embalmers use, an object being to provide an electrically driven pump by means of which embalming fluid may be ejected under suflicient pressure to be thoroughly distributed throughout the body of a corpse with a minimum number of injections.

Another object of the invention is the provision of a device of the above character which includes a motor driven pump and a fan for cooling the pump, with the motor, fan and pump constructed as a unit so that they may be conveniently supported, with means to support the unit to absorb vibration and noise, so that the device will operate quietly, which is essential in devices for this purpose.

Another object of the invention is the provision of means for conveniently and accurately controlling the speed of the motor and operation of the pump so that pressure of the fluid may be accurately controlled.

With the above and other objects in view, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevation of the invention.

Figure 2 is a top plan view.

Figure 3 is an elevation at right angles to Figure 1.

Figure 1 is an enlarged front view of a slightly different form of the invention, parts being broken away and shown in section.

Figure?) is a fragmentary top plan view of the subject matter of Figure 1.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a base which may be in the form of a hollow platform, while 11 indicates a yokelike support which is secured to and rises from the base.

The invention includes a motor, the housing of which is indicated at 12, while the shaft of the motor is indicated at 13. Arranged within the motor housing and mounted upon the shaft 13 are fan blades; 14, while positioned within the reduced end of the housing s'a' rotary pump 15 which'is also mounted upon the'shaft '13. The fan acts to cool the pump andto assist in this cooling operation, the housing is" provided with a plurality of radially disposedveins or fins 16.

As it will be apparent, the motor, fan and pump are constructed as a single-unit and in order to support this unit from the base 10 and support 11, the housing 12 carries a hanger loop 17 which engages over the yokelike support 11 This loop will also serve as a handlewhen the unit is detached from the su port. This removal of the unit may be leoft'ected by detaching the support from the ase.

The pump is provided with an inlet 18 which may be connected by means of a tube a 19 with a source of fluid supply, while an outlet 20 provides means for connection with a discharge tube 21. A pressure gauge 22 is interposed between this tube and the outlet.

20, so that the pressure of the pump may be indicated.

The base 10 carries lugs 23 and 2 1 for conductors 25 and 26 to provide means for supplying current to the motor. A rheostat 27,

mounted upon the base is connected in circuit V with the motor so as to regulate the supply of current thereto. A switch 28 is also included in the motor circuit.

In order to reduce vibration and eliminate noise, the unit which includes the motor, the

fan and the pump, is connected with the support 11 by means of springs 29, while a spring 30 connects the unit with the base 10. The spring 30 is adjustably secured to the unit and for this purposethe latter is provided with a flange 31 having spaced apertures check valve controlled 35. The piston 36 operates within this cylinder and this piston is connected by means of a rod 37 with a crank arm 38 which is fast upon the motor shaft 13. The crank arm operates within the housing 39 which is provided with screen covered openings 40 so as to provide cooling means, While the cylinder 33 is provided with cooling fins 41.

The invention is susceptible of various changes in its form, proportions and minor details of construction and; the right is herein reserved to make such changes as properly fall within the scope of the appended claimJ Having described the invention what is claimed is In an electrically operated pump, a base, a

yoke-like support secured to and rising from e base, a motor including a, housing positioned within the yoke above the base, a hanger loop secured to the motor housing and engaging over the yoke, springs connecting the houslng and yoke andhousing and base to yieldingly hold" the motor housing in horizontal position, a motor driven fan included insaid housing, a motor driven pump also included in said'housiIlg means to connect the pump with a source of'fluid supply, and a discharge outlet for the pump.
